Abstract
The utility model relates to a jig, and particularly discloses a tin stealing jig for wave soldering. For settling problems of batch bridge connection, trouble in production and manufacturing, and low production efficiency caused by a fact that tin removing cannot be performed on components with oversmall distance in the prior art, the tin stealing jig comprises the components of: a base, a tin stealing sheet and a hollowed area. The base is internally provided with the hollowed area. The hollowed area is used for exposing a soldering pad for placing the components placed on a PCB. The shape of the hollowed area is matched with the position of the soldering pad of the PCB board. The tin stealing sheet is fixed on the base for stealing excessive tin on pins of the components. The tin stealing jig provided by the utility model is suitable for the technical field of wave soldering.
Description
Technical field
The utility model relates to a kind of tin tool of stealing, and relates in particular to a kind of tin tool steathily for wave-soldering.
Background technology
Wave-soldering refers to and allows the solder side of card directly contact and to reach welding object with high-temperature liquid state tin, its inclined-plane of high-temperature liquid state tin maintenance, and make liquid tin form the phenomenon of the similar wave of a lot of by special device.In current wave-soldering operation, after need to directly inserting components and parts in PCB aperture, operating personnel crosses stove, serve as after stove because the overstocked components and parts of spacing cannot drag tin, cause crossover in batches, and easily produce and scrap in the time that components and parts are keeped in repair, bring puzzlement to the manufacturing, affect production efficiency.
Utility model content
The purpose of this utility model is, a kind of tin tool steathily for wave-soldering is provided, and solves above technical problem.
The technical problem that the utility model solves can realize by the following technical solutions:
Described in the utility model for wave-soldering steal tin tool, comprising: base, steal tin sheet and vacancy section,
In described base, be provided with vacancy section, described vacancy section is in order to expose the pad of placing components and parts to be welded on pcb board, and the shape of described vacancy section and the pad locations of described pcb board match,
Steal tin sheet, the described tin sheet of stealing is fixed on base, in order to steal tin unnecessary on described component's feet.
In a preferred embodiment, the described tin sheet of stealing is the tin sheet steathily that adopts latten(-tin) to make.
In a preferred embodiment, the described tin sheet of stealing is folded-plate type, and described tabs is horizontal tabs.
In a preferred embodiment, described one end of stealing tin sheet is screwed on base, and described the other end of tin sheet steathily and the beeline of described pin are: 0.5mm～2mm.
In a preferred embodiment, described tin sheet is steathily multiple.
In a preferred embodiment, described base is the base that adopts the synthetic one-tenth made of stones of ESD static.
The beneficial effects of the utility model:
Owing to having adopted technique scheme, vacancy section is positioned on the pad of components and parts to be welded on pcb board, in wave-soldering process, steal on pcb board tin unnecessary on component's feet by stealing tin sheet, the problem of having avoided components and parts cannot drag tin, reduced manpower, shortened the materials and parts repair welds time, adopt steal tin tool make production efficiency by before 65% be promoted to 95%, ensure product quality, improved production efficiency.
Brief description of the drawings
Fig. 1 is the overall structure schematic diagram of stealing tin tool for wave-soldering described in present embodiment;
Fig. 2 is the enlarged drawing that present embodiment is stolen tin sheet and Pin locations relation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
Embodiment one, illustrate present embodiment in conjunction with Fig. 1 and Fig. 2, present embodiment is stolen tin tool for wave-soldering, comprising: base 1, steal tin sheet 2 and vacancy section 3,
In base 1, be provided with vacancy section 3, vacancy section 3 is in order to expose the pad of placing components and parts to be welded on pcb board, and the shape of vacancy section 3 and the pad locations of pcb board match,
Steal tin sheet 2, steal tin sheet 2 and be fixed on base 1, in order to steal tin unnecessary on component's feet.
Between the pin 4 of the components and parts in present embodiment, distance is less than or equal to 2.54mm, and these components and parts have: transformer, network interface and optical-electric module etc.Accommodation can be made according to the requirement of product in vacancy section 3.
Embodiment two, the difference of stealing tin tool for wave-soldering described in present embodiment and embodiment one is, steal tin sheet 2 and be adopt that latten(-tin) makes steal tin sheet.
Embodiment three, the difference of stealing tin tool for wave-soldering described in present embodiment and embodiment two is, steals tin sheet 2 and is folded-plate type, tabs is horizontal tabs.
Embodiment four, the difference of stealing tin tool for wave-soldering described in present embodiment and embodiment two is, the one end of stealing tin sheet 2 is screwed on base 1, steals the other end of tin sheet 2 and the beeline of pin 4 to be: 0.5mm～2mm.
Embodiment five, the difference of stealing tin tool for wave-soldering described in present embodiment and embodiment two is, it is multiple stealing tin sheet 2.
Embodiment six, the difference of stealing tin tool for wave-soldering described in present embodiment and embodiment one is, base 1 is for adopting the base of the synthetic one-tenth made of stones of ESD static.
Wherein, ESD(Electro-Static discharge) " static release ".ESD is the subject of generation, harm and the electrostatic defending etc. with the research static that have formed since mid-term in 20th century.Therefore, be accustomed in the world the equipment for electrostatic defending to be referred to as ESD, Chinese is electrostatic impedor.
The shape of stealing tin tool for wave-soldering can be made accommodation according to the requirement of product, ESD static is synthesized to stone high-temperature material according to the bond pad shapes of components and parts to be welded on pcb board, polish vacancy section 3, vacancy section 3 is positioned on the pad of components and parts to be welded on pcb board, the pin 4 of components and parts is exposed in vacancy section 3, make tin sheet 2 steathily with component's feet 4(as Fig. 2) distance remain on 0.5mm-2mm between, prevent pin 4 with steal tin sheet 2 weld together after stove.Carried out stove scolding tin by wave soldering machine, thereby reach the effect of dragging tin, and improved product yield, human cost reduces.
The foregoing is only the utility model preferred embodiment; not thereby limit execution mode of the present utility model and protection range; to those skilled in the art; the scheme that being equal to of should recognizing that all utilization the utility model specifications and diagramatic content done replaces and apparent variation obtains, all should be included in protection range of the present utility model.
